@ormom8 Yes! Aircrete presents us with new paradigms of creativity. You could just tack your wiring up to the inside of the walls and finish with the earthen or "other" finish. Then if you need to change it just scratch them out. They would only be an inch or so deep. and re-plaster. The conduit would provide some protection from something banging into the walls and shorting out a wire. I encourage everyone to NOT create new "Aircrete rules boxes". Live creatively and outside the "boxes"
